Mattison spent three seasons coaching in the NFL, as linebackers coach and defensive coordinator for the Baltimore Ravens from 2008-10. He describes the 6-foot-1, 292-pound tackle as "so explosive, and so fast," and perhaps more importantly, a true fit in the NFL.

But an irregular electrocardiogram detected in March at the NFL Scouting Combine could test that, with Hurst's draft stock sliding from a near-unaninmous first-round pick to a early-to-mid second round-pick slot.

Hurst has since been cleared medically by cardiologists at the University of Michigan and Harvard University, and participated in Michigan's pro-day event last month.

"If I didn't think that, I would never do that to some of the NFL coaches," Mattison said. "I'd be honest with them. And I think my players know that, that I'm going to be honest with whoever asks me.

"I'm very excited about his opportunities."

Hurst was a consensus first-team all-Big Ten selection in 2017, earning All-American honors for his stellar play at defensive tackle. He had 61 tackles, including 14 1/2 for a loss, and five sacks while adding three quarterback hurries and two pass breakups.
